Pob zeb Superplasticizer

Cov dej pob zeb txo tus neeg sawv cev yog ib yam khoom siv hauv tsev. Tshuaj additives. Nws yog dav siv tam sim no. Nws yog siv rau pob zeb ua dej txo tus neeg sawv cev. Lub npe tshuaj yog: sodium methylene dimethyl dinaphthalene sulfonate polymer.

Txoj kev tsim khoom

Siv methylnaphthalene thiab sulfur trioxide ua raw khoom, undergo sulfonation, condensation, neutralization thiab lwm yam tshuaj, thiab thaum kawg qhuav kom tau cov khoom tiav.

Cov degree ntawm polymerization ntawm cov dej reducer feem ntau yog hais txog 6-12, uas yog: n=6-12, yog tias qhov degree ntawm polymerization yog 1-3, nws yog siv los ua dispersant.

Kev faib tawm ntawm cov dej ua kom txo cov neeg ua haujlwm (tau txais los ntawm lub vev xaib ntawm Guangxi Zhuoyu Cov Khoom Siv Hauv Tsev) [1] Cov khoom siv pob zeb tuaj yeem muab faib ua plaub pawg raws li lawv lub luag haujlwm tseem ceeb:

1. Admixtures los txhim kho rheological zog ntawm cov pob zeb sib tov: nrog rau ntau yam dej reducers, cua-entraining agents thiab twj tso kua mis, thiab lwm yam.

2. Admixtures rau kev kho lub sij hawm teem thiab hardening kev ua tau zoo ntawm pob zeb: nrog rau cov retarders, thaum ntxov lub zog, accelerators, thiab lwm yam.

3. Admixtures los txhim kho lub durability ntawm pob zeb: nrog rau cov cua-entraining agents, waterproofing agents, thiab xeb inhibitors.

4. Admixtures los txhim kho lwm yam khoom ntawm pob zeb: nrog rau cov khoom siv cua nkag, cov neeg ua haujlwm nthuav dav, cov tshuaj tiv thaiv kab mob, cov tshuaj pleev xim, cov tshuaj tiv thaiv dej, thiab cov twj tso kua mis.
